On Being the Right Size as an Animal with Plastids [PDF]

open access: yesFrontiers in Plant Science, 2017
Plastids typically reside in plant or algal cells—with one notable exception. There is one group of multicellular animals, sea slugs in the order Sacoglossa, members of which feed on siphonaceous algae.

Role of body size and shape in animal camouflage

open access: yesEcology and Evolution
Animal camouflage serves a dual purpose in that it enhances both predation efficiency and anti‐predation strategies, such as background matching, disruptive coloration, countershading, and masquerade, for predators and prey, respectively.

Behavioural causes and consequences of sexual size dimorphism in an apex predator species. [PDF]

open access: yes
Individual differences within populations in a range of phenotypic traits are hypothesised to have important ecological and evolutionary implications. Variation in individual growth rates that result in corresponding variations in body sizes, including ...

Running Springs: Speed and Animal Size [PDF]

open access: yesJournal of Experimental Biology, 1993
ABSTRACT Trotting and hopping animals use muscles, tendons and ligaments to store and return elastic energy as they bounce along the ground. We examine how the musculoskeletal spring system operates at different speeds and in animals of different sizes.

The size of the largest land animal [PDF]

open access: yesJournal of Theoretical Biology, 1986
The upper mass limit to terrestrial animals is studied using physical arguments and allometric laws for bone and muscle strength and animal locomotion. The limit is suggested to lie between 10(5) and 10(6) kg. A possibility for a still higher mass, in case of new adaptations, is not excluded.

Size and shape of terrestrial animals

open access: yesThe 9.5th International Symposium on Adaptive Motion of Animals and Machines (AMAM2021), 2021
Natural selection for terrestrial locomotion has yielded unifying patterns in the body shape of legged animals, often manifesting as scaling laws. One such pattern appears in the frontal aspect ratio. Smaller animals like insects typically adopt a landscape frontal aspect ratio, with a wider side-to-side base of support than center of mass height ...

Sexual selection and sexual size dimorphism in animals [PDF]

open access: yesBiology Letters, 2021
Abstract Sexual selection is often considered as a critical evolutionary force promoting sexual size dimorphism (SSD) in animals. However, empirical evidence for a positive relationship between sexual selection on males and male-biased SSD received mixed support depending on the studied taxonomic group and on the method used to quantify

ANALYSIS OF THE FACTORS THAT INFLUENCE CONFORMATION TRAITS IN BLUE FOX (ALOPEX LAGOPUS L.)

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The present work aims at the analysis of the factors that influence animal size and fur quality in blue fox (Alopex lagopus L). The data proceeds from a breeding farm situated in central Poland and concerns three years.
